Mrs. Younge was the companion hired by Fitzwilliam Darcy to preside over an establishment in London for his fifteen-year-old sister Georgiana after she left school; however, he had been unhappily deceived in her character and discovered too late that she had a prior acquaintance with George Wickham, their late father's godson and favorite, who had turned out very bad and developed a resentment for Darcy.
She took her charge to Ramsgate in the summer where she reacquainted Georgiana with Wickham. With her connivance and aid, he set about seducing Georgiana into an elopement that would grant him full control of Georgiana's thirty thousand pounds and revenge himself upon Darcy. When Darcy unexpectedly joined them, Georgiana told him everything since she looked up to him as a father. Darcy wrote to Wickham, and he removed Mrs. Younge from her charge.[1]
When Wickham eloped with Lydia Bennet, Mr. Darcy tracked down Mrs. Younge in London. She was then living in Edward-Street and letting lodgings. Wickham first came to Mrs. Younge for a place to stay, but she could not provide him one. Lydia's aunt, Mrs. Gardiner, later implies to Lydia's sister, Elizabeth, that Darcy had to bribe Mrs. Younge to find out where Wickham and Lydia were, because she knew where they were staying, and Mr. Darcy found them soon after.[2]
